Specification of Letters Patent.

Application filed November 12, 1920. Serial, No. 428,515.

. To all whomit may concern:

Bait known that I, FRANK P. WILLIAMS, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Drinking-Fountain Attachments for Bibbs or Faucets, of which the following is a specification.

This invention relates to a drinking fountain attachment for securing to ordinary bibbs or faucets. It may be also used as a combined filter and drinking fountain attachment. It is-simple in operation and unusually simple to manufacture, and in these particulars it is consideredrather unique.

In, the drawings,-- Fi re 1 is a side elevation of a bibb provide with the attachment.

Fig. 2 is a vertical section of the attach-' ment.

Fig. 3 is a plan view of the attachment.

The device comprises simply a threaded filter cap (1 provided with a filter screen 6. Fitted around this is a piece of rubber tubing 0 having its lower end provided with a pair of recesses d, cl cut into the interior wall of the material at diametrically opposite points. An aperture is made in the side of the. tubing and an elbow 0 with a flared-out inner end 7 is inserted from the inside and forced out as far as it will go. The hole through which this is forced is relatively small so that when the elbow is drawn out to the extreme position permitted by the flared-out portion f of the inner end a water-tight joint between the elbow and the tube is assured. On the top of this elbow is mounted'a porcelain cap gr which'has an opening it therethrough.

his forms the bubbling fountain.

Now, of course, when the rubber tube is left in its natural position the water will simply pass down through the tube. When it is desired to use the drinking fountain, one sirn 1y grasps the lower end of the tube and col apses it as shown in Fig. l. The collapsing of the lower end of the tube is facilitated by the recesses 03. This means simply that the walls are ressed together. Obviously in this position little or no water can get through. Consequently the water pressure will cause the water to bubble up through the fountain h where a drink may be had. Of course, the filter screen 6 is not the bibb is necessary in order to carry the drinking fountain, .the use of the filter screen in the attachment is an added feature. If the bibb is not provided with an externally threaded end the rubber tube may he slipped right over the smooth end of the bibb. Of course, the rubber tube is made small enough so that considerable stretching is necessary, and this avoids the Wtbfil pressure from. forcing the attachment 0 What I claim is:
